SPECIFICATION forming part 0f Letters Patent t).1 703,372, dated July 1, 1902. Application tiled November 4, 1901. Serial No. 81,134. (No model.)

To @ZZ whom t may conceive:

Be i't known that I, PETER JOSEPH4 BEIsEL,

a citizen of the United States, residing at Al' lentown, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Door-Operating Device, of which the following is a specification.

Myinvention relates generally to mechanism for opening doors, and has for its principal object to provide improved mechanism of this class especially applicable to the opening of the doors of horse-stalls in nre-engine or patrol houses, such mechanism being operable by the general alarm system, but provided with handoperating means for use in emergencies or when practicing the horses.

With this and other objects in view the invention consists in the improved construction, arrangement, and combination of parts hereinafter described, illustrated in the aci companying drawings, and particularly point ed out in the appended claims.

In thedrawings, Figure l'is a View in elevation of a series of doors equipped with opening mechanism arranged and constructedI in accordance with my invention. Fig. 2 is a detail view, on an enlarged scale, of one of the door-latches. Fig. 3 is a detail viewillustrating the means employed for causing one door upon opening to release the latch of another door. Fig. 4'is a sectional elevation, on an enlarged scale, illustrating the operating -weight andthe electromagnetic trip therefor.- l Fig. 5 is atransverse sectional elevation of the same on theline 5'5 of Fig. 4. Similar numerals'of reference are employed to designate corresponding parts throughout the several figures of the drawings. f

Referring to ythe'drawings, 10,11, 12,an 13 indicate the doors of `a series of stallsarranged side by side, as is usual in hre-engine or patrol houses, and 14 indicates a door unconnected with the opening.` mechanism for ingress or egress of the attendants. Y

Each of the stall-doors 10, 11, 12, and 13 is provided with an opening-spring, as at 16,17, 1S, and 19, and a latch-bar, a`sat-20,21, 22, and 23, all of said latch-bars and all of their catch-bolts 24, 25, 26, and 27 being duplicates in construction. In Fig. 2 is illustrated in detail one of said latch-bars and its operatingbolt, selecting the bar 20 on -door lOwith the loolt 24 for this-purpose.v In this figure it Will be seen in detail that the latch-bar 20 is rigidly secured to the door 10 inf a horizontal position and that it is held behind the lower end of the bolt 24 whenthe bolt is lowered,

said bolt working vertically in a keeper 28 on the door-jamb, there being a similar keeper and 36, respectively, and the bolt-26 is con? nected by ay vertical rod 317to`a bell-crank lever 35. The upper ends of.` th'e bell-crank levers 33, 34, and 36 are pivotally connected to a main operating-rod 37, mounted-in suitable supporting-brackets 38 and extending over the whole series of doors. The rod 37 is normally maintained in position to hold all of the bolts in lockingposition'by an expan-` sion-spring 39 'at one end.

\ 'The bell-cranklever 35 has thel upper end lof its vertical arm pivot-ally connected to a short horizontally-movable rod '40, connected 'at its oppositeend'totheuppere'nd of a'bar 41, pivoted to the frame of the door 11 and provided with an arm 42 yinthel path ofthe door 11 whenopening and guided between a bracket 43 and the door-framef When the rod 3.7 is moved horizontally in 1 the direction of the arrow against the stress of the sprin g 39,`the latch-bolts are all drawn upwardly, releasing the latchesy and permitting the several door springs to open f the To perxnit'of this opera-` doors of the stalls. tion by handw'hen it is desired to practice the horses, abell-crank lever 441i'spivoted to the wall and has its upper end pivotally connected tothe 1od'37, and the en'd of' its horizontal arm carries a cordor rod'45,"`t o .which is attached a suitablehandlef46. Thepoperating-rod 37 is, however, usuallyoperatedl-by the electric current which sounds the alarm or by a local current'actuatedby'a relay in the alarm-circuit, and this is effected 'bylfthe mechanism illustrated more clearly in Figs. 4 and ICO 47 indicates a bell-crank lever, the upper end of the vertical arm of which ispivotally connected to the rod 37, and the end of Whose 'horizontal arm is provided with a pin 50,

adapted to a vertical slot l in the upper end of avertical rod 48. The lower end. of the rod 48 passes through an opening in the top of the box 52 and is secured to a-weight 53,

sufliciently heavy to overcome the force of the spring 39 and move the rod 37 to the left, as before mentioned'. This weight 53 is ordinarily supported by a pivoted bar 54 and falls when said bar is released. The box 52 is divided by a partition 55 into two compartments, in one of which the weight 53 is situuated. In the other compartment is placed a bipolar electromagnet 56, connected in the alarm-circuit or, as previously described, in a local circuit operated by a relay in the alarmcircuit. In this compartment is also situated a pivot bar or shaft 57, onrwhich is fulcrumed a trip-lever 58, having at its lower end a tongue or finger 59 to engage under the magnets 56, andl when the circuit is closed the armature is attracted and held andthe bar 54 is locked in position and holds the weight raised. l Should the circuit be broken either by the sounding of the alarm or by the operation of a push-button or other circuitbreaker, a spring 61 will act to pull the trip-r lever from the bar 54, the latter swinging on its pivot-point and permitting the Weight 53 to fall. When the Weight falls, the rod 48 is 'carried with it, and owing tothe slotted connection between the rod and bell-crank lever 47 the weight will have lacquired sufficient momentum to overcome the resistance of the spring 39 by the time the end of the slot comes into contact with the pin 50 on the bellcrank lever 47. This s lottedconnection also serves to permit of the movement of the various parts by the hand-operated rod or cord "45 Without disturbing the rod 4S.

4In order to retain 'the Weight in the elevated position during tests or when it is desired to prevent the'operation of the dooropening devices by the alarm circuit, the lowerportion of the partition 55 is provided with a pivoted arm 63, which may be moved under the weight-supporting bar 54 to retain the'same in locking position.

Whilethe construction `herein illustrated and described is the preferred form of the apparatus, it is obvious that many changes in the form and arrangement of parts may be made Within the scope of the claims Without departing from the spirit or sacrificing any of the advantages of the invention. i
